Abstract


Communication is an important part of the distribution automation system , the control center of the distribution network to achieve data transmission , remote terminal and the necessary means to capture and control the composition and function of the realization of the distribution automation system plays a very important role . Distribution automation can choose a variety of communication technologies : optical fiber communication , power line carrier communications, wireless communications , and so on . Decided due to the characteristics and requirements of distribution automation communications impossible using a single communication technology in the communication system , and the choice of different communication technologies and programs a great influence on the design of real-time , reliability and validity of the communication system , construction and operation and maintenance costs are very different. This article describes the structure, function and role of the distribution network automation , summarizes the characteristics of the communication system of distribution automation and the general requirements , the communication protocol for distribution automation and distribution automation communications needs analysis . Fiber private network communication power line carrier communication and wireless public network communication , wireless private network communication and other communication technology communication theory, technical features , networking , performance focused on communication technology . Constructed in networking mode on the existing several common communication technology , performance studies and comparisons on the basis of distribution automation communications program based on Ethernet Passive Optical Network (EPON) technology from the communication medium , group network structure , communication interfaces and bandwidth , business protection capacity , construction costs and other aspects of the feasibility analysis . For communication security issues , given the communication encryption scheme based AES algorithm EPON system ; and EPON with the topology of the network communication and construction cost effectiveness analysis , and finally arrive at a more suitable distribution automation communications EPON topology , believe that certain reference value of the renovation project of the electricity distribution in the current implementation of the communication network .
